Our discovery and physical characterization of the most distant galaxy candidates at z ~13 named HD1 and HD2 are described in these papers:
- Pacucci et al. (2022): Are the newly-discovered z~13 drop-out sources starburst galaxies or quasars?
- Harikane et al. (2022): A Search for H-Dropout Lyman Break Galaxies at z ~ 12-16
This discovery has generated a huge amount of press coverage, with several press releases from different institutions around the world, including the Center for Astrophysics | Harvard & Smithsonian. The news was made public on April 7, 2022.
According to an analysis performed by the press office of the Center for Astrophysics, as of April 13, 2022, the news reached ~1.5 billion readers worldwide. It appeared in dozens of countries and was translated into multiple languages, including Portuguese, Italian, Japanese, Chinese, Dutch, Hindi, Spanish, German and Polish.
